Update

Article from December 5, 2025

There was a time before my website existed. I realize that with this news item. Sparkverb is a beautiful-sounding algorithmic reverb that was released back in 2013. That was 12 years ago, and the plugin is still there and being maintained.

Now, excellent news. UVI has released Sparkverb 1.5, another free update for its reverb plugin that puts on new clothes and more.

Sparkverb 1.5 is a free update that introduces a completely redesigned interface, which more closely matches the look of today’s UVI plugins. According to UVI, it also matches the aesthetic and workflow refinements introduced with their Bloom reverb. 

To me, it looks more streamlined and more straightforward to use. In addition, Sparkverb 1.5 includes an updated factory preset library with 50 new presets, including some from Venus Theory.

They offer a broader palette of ready-to-use reverbs – ideal for mixing, sound design, and cinematic atmospheres.

The core of Sparkverb 1.5 remains untouched and delivers the same wide range of reverbs from natural rooms to infinite shimmering ambiences with efficient CPU usage in mind. You can still use the frequency-based spectral editor to craft the perfect reverb sound. 

One of the highlights of the plugin, the preset voyager feature that allows you to morph between presets, is still on board. Same as the randomization/mutation features, freeze, modulation, and more.

First Impression

Releasing such an update after 12 years, and for free on top, is very welcome. Thank you, UVI. I hope Sparkverb for iOS also gets this new UI.

UVI Sparkverb 1.5 is a free update for existing users. To celebrate the release, Sparkverb and Bloom are available at a special price of $39 / 39€ each (regularly $79 / 79€) through December 15th, 2025. It’s also part of the SonicPass subscription and SonicBundle.

Sparkverb runs as a VST, VST3, AU, and AAX plugin on macOS (native Apple Silicon + Intel) and Windows.
